Introduction

What entails a flagship smartphone? The question posed here might be a simple one, as most companies put their best showing into one, singular product. To the Korean giant in Samsung, however, the idea of a flagship phone is now spread not to only one device, but surprisingly two instead. This notion of two variants of a flagship phone was first introduced last fall during IFA 2014, where alongside the announcement of the Samsung Galaxy Note 4, Samsung decided to out the Samsung Galaxy Note Edge.

Following forth with a similar move, the company decided that it would be beneficial to announce a second version of its flagship smartphone in the Galaxy S6. Rather than sporting one curved edge like the Note Edge last fall, the Samsung Galaxy S6 edge favors a uniform approach by sporting a dual curved display – where the left and right sides are subtly curved. No doubt, it’s a strange direction, one that can also be viewed as foreign, but it’s the perfect complement to the line’s totally new redesign.

As we’ve experienced on the Note Edge, the curved area not only adds a unique aesthetic quality, but also a functional tool as well. With the Galaxy S6 edge, though, the benefits of going with a dual-curved display are mostly of aesthetic quality, dwindling the importance of its functional aspect.

Design

The new, premium design is profound, but the dual-curved display helps to increase its aesthetic appeal.

Alright, we absolutely adore the new direction Samsung has decided to go with the design language of its flagship series! Plastic is out, replaced instead by Gorilla Glass 4 surfaces held together by a slim metal trim bezel lining the entire length of its edges. The result, not surprisingly, is a smartphone that radiates with premium qualities we have never experienced before in a Samsung product.

To be fair, though, this new design change first started with the Samsung Galaxy Alpha, which eventually became the design footprint for Note 4. With those aforementioned devices, Samsung choose to add a subtle presence of premium in its designs by adding metal trim bezels. However, for the Galaxy S6 line, Samsung went back to the drawing board and delivers something so immaculate and refreshing.

Indeed, the S6 edge is fashioned to look identical to the S6, but there’s something else more that makes its design look superior. What is that you ask? Well, it’s specifically due to the dual-curve display it’s sporting. Unlike the Note 4 Edge, the S6 edge has more of a subtle curve – so it doesn’t slope down as much as the curved edge of the Note Edge. The implementation makes the handset appear deceptively thinner than it is, although, it becomes sharper feeling in the process because of how the metal bezel is trimmed down on those edges.

Picking it up for the first time, there’s that sense of fragileness due to its sleek frame and glass surfaces, but the dual curved nature of the phone exemplifies the aesthetics to a higher degree than the standard S6. As we’ve said, there’s a sharper feel due to this, which makes it sit in a slightly more uncomfortable manner in the hand, compared to the regular S6. Still, swiping across the curved display feels natural – as if our thumbs prefer I more than the usual “flat” ending of a smartphone's screen.

So far, the Galaxy S6 line’s new design language is much better than before, but there were necessary compromises needed in making this phone. We can’t deny that we enjoy its premium feel, but it sheds some of the staple qualities of the S5 before it – like its water resistant construction, expandable microSD card slot, and removable battery.Now, as much as we adore the premium feel of the phone, it’s just a magnet for smudges and fingerprints. Trust us, it’s tough keeping it clean looking. Available in an assortment of colors, it’s mesmerizing how light bounces off its surfaces to give an even more dazzling, shimmering effect. Out of all the colors, the white version manages to maintain a cleaner look, just because fingerprints and smudges are less noticeable.

Looking around the phone, it’s sporting some of the same set of ports and buttons throughout its frame. The separated volume controls are placed on the left edge, the power button on its right, microUSB 2.0 port, 3.5mm headset jack, microphone, and internal speaker on its bottom, and finally the IR blaster, noise-cancelling mic, and nanoSIM slot placed on its top edge. Distinctively a Galaxy phone, the same home button is present beneath the display – flanked by the Recent Apps and Back capacitive buttons.

Fingerprint sensor

Indeed, the home button incorporates the unit’s fingerprint sensor, but this year’s implementation is vastly better, since it now follows the operation we’ve seen employed by the iPhone. Rather than swiping down for it to register our fingerprint, all that’s needed now to unlock the phone is to gently press it over the home button. It’s simple and effortless, whereas before, it was a frustrating process at times. Getting it set up is similar to Apple’s Touch ID sensor, as we’re required to gently press our finger over the sensor multiple times – where it’s mapped entirely for accuracy.

Rounding things out, the Galaxy S6 edge is armed with a new 16-megapixel rear camera, which is the only thing in the back that juts out from the rest of the surrounding area – causing it to come in contact with surfaces when it’s laid down. This presents an issue, one that’s exemplified because of the handset’s top-heavy feel, just because if you’re not careful and try to prop the phone against something, there’s still a distant possibility it can fall over and somehow mess with the lens covering the camera. And finally, we find the LED flash and heart rate sensor nearby.

Display

Clearly pushing the envelope, this quad-HD display is not only rich with detail, but it’s the most color accurate AMOLED display to grace a phone to date.

Samsung didn’t stop at just the design when it comes to leaving a lasting mark on us, as the display has undergone a similar level of treatment. Keeping the same screen size as its predecessor, Sammy moves forward in that incremental manner by gracing the Galaxy S6 edge with a drool worthy 5.1-inch 1440 x 2560 (QHD) Super AMOLED panel. In all honesty, the decision to go forward with quad-HD resolution was expected – more so when it’s increasingly becoming the resolution of choice amongst Android flagships.

Going with this, you can imagine that this leads to one staggering pixel density, we’re talking about a mark of 577 ppi! That’s mind-blowing to say the least, which leads to a display that’s rich with detail and exceptionally sharp looking. Most folks would be hard-pressed to distinguish how much more detailed this panel is than others with 1080p resolution, especially from a normal distance, but it goes to show that Samsung won’t settle for anything but being class-leading.

Besides its detail superiority, its Super AMOLED panel follows in fashion to the improvements we’ve seen exhibited already by the Note 4 – thus, shedding the inaccuracies of the Galaxy S5 display, replaced by the color accurate AMOLED panels in other more recent Samsung devices. The company’s continued fine tuning of the display technology has given the Galaxy S6 edge, alongside its brother, as having the best Super AMOLED display to date.

Without factoring in its dual-curved nature, one would suspect that this is exactly similar to the standard S6’s Super AMOLED display. Our benchmark tests reveal otherwise, as the S6 edge boasts a color temperature of 6800K, a slightly colder toned panel than the 6550K color temperature of its sibling’s screen. Putting the two next to one another, the slight difference in color temperature is apparent, since the Galaxy S6 edge’s panel appears cooler. It’s not bad quite honestly, especially when it’s close to reaching that ideal reference value of 6500K.

Setting the display to basic mode, as opposed to adaptive, which changes the contrast, color saturation, and other parameters depending on what’s being shown on screen, the Super AMOLED panel is extremely color accurate. It’s revealed through the color gamut chart, as each color gradient closely matches the reference points throughout the chart. Blues look blue, reds look red, and greens appear green – so the result here is a display with very high color accuracy.

Oddly enough, the S6 edge’s maximum brightness output is vastly less than the S6’s radiance when the brightness is manually adjusted to the highest setting. At that mark, the S6 edge achieves an output of only 172 nits, in comparison to the S6’s 332 nit brightness at the same level – albeit, the difference is minimal once it’s set to automatic brightness and high contrast mode jumps in. Only then is it able to closely match its sibling's mark! Specifically, the S6 edge’s Super AMOLED display shines brilliantly at 553 nits, which is oh so close to the 563 nit brightness produced by its brother. In any event, the achievement deserves adulation, mainly because it allows for good visibility when the sun is present – instead of being washed out and unviewable.

Dual-curved edges

Undeniable to say the least, the dual-curve display is what separates this model from the standard Galaxy S6. Therefore, what’s so special here? Much like the Note Edge before it, the subtle curved edges are used for a variety of things – though, we believe it’s there more for the aesthetics than function.

When it’s off, we can simply swipe back-and-forth from one of its sides to activate various information tickers, like those that offer stock prices, news, notifications, the time, and more. There are a few that are available out of the box, but the collection can be supplemented by downloading additional ones. Frankly, as much as it’s useful to glance at it, the limited space that’s available to the feature makes it tough to distinguish things if we’re not very close to the phone. However, we do appreciate that the information ticker can automatically be set to turn on for a duration of time at night.

Besides that, the dual-curved edges also provide us instant access to People Edge – a small ribbon that offers us access to up to five favorite contacts. From the lock screen, the convenience factor is there because it’s accessible at a moment’s notice. However, if you opt to have a security lock of some kind, the feature might not be available – that’s unless you enable the lock screen to show all notifications.

Now, there’s something interesting that happens when those chosen “favorite” contacts call us up. When the phone is placed face down, where the display is in contact with the surface, the edges of the phone will light up in a variety of colors to indicate who is calling. On one hand, we appreciate this discrete way of telling us who is calling, but its effectiveness is reduced if the phone isn’t placed on a glass or reflective surface – since the colors won’t be able to bounce off surfaces so much to produce its light show.

At the end of the day, the dual-curved display is here on the Galaxy S6 edge mostly for the aesthetics.

The CIE 1931 xy color gamut chart represents the set (area) of colors that a display can reproduce, with the sRGB colorspace (the highlighted triangle) serving as reference. The chart also provides a visual representation of a display's color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The 'x: CIE31' and 'y: CIE31' values in the table below the chart indicate the position of each measurement on the chart. 'Y' shows the luminance (in nits) of each measured color, while 'Target Y' is the desired luminance level for that color. Finally, 'ΔE 2000' is the Delta E value of the measured color. Delta E values of below 2 are ideal.

The Color accuracy chart gives an idea of how close a display's measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.

The Grayscale accuracy chart shows whether a display has a correct white balance (balance between red, green and blue) across different levels of grey (from dark to bright). The closer the Actual colors are to the Target ones, the better.

I think if the price would be the same everyone would go for it.
But the $150 you need to cash for something that is just an aesthetic difference it's going to be a tough pill to sallow for most of the people.
But if you have the money, I understand that you would rather get the edge.

I don't really have a problem with the battery being non-removable but I already have multiple high end SD cards and the fact that they are charging a huge premium to get more storage is a hard pill to swallow. This will turn many away when Android has other options. Not bashing.... everyone has their own opinion.

It means nothg about how fast your sd card are, by just adding an sd card reader the note4 r and w slower the then 1+1 and way slower than the iPhone, it does big time damage to the bandwidth of any phone tha adds it, the s6 uses ufs 2.0 that needs more bandwidth to work so sd card reader can not be added, this then make it way more than 2x the speed of the iphome 6 r and w speeds and removes the lag on the phone

I own both the Note 4 and OnePlus One and I found that actually use very little of my microSD card for storage (none on the OnePlus obviously). I have a Google Play Music (All Access) subscription and also listen to most of my music on Soundcloud so most of my music is streamed and not on my phone. All my photos and videos are auto backed up on Photos/Picassa/Google+ so I can safely delete them from local storage on my phone if needed. I also have 1.117TB storage on Google Drive (15GB included +2GB free from updating security settings+100GB I pay for +1TB for 2 years promotion for buying a Chromebook).

As far as battery is concerned, I have invested in an external battery charger and I already have 2 Qi chargers (for my Note 4 with Qi charging back and Nexus 7 2013) that I can use.

More likely I won't buy the S6/Edge because I'm a Note buyer (maybe my wife will since she's due up for a new phone), but if they did this for the Note, I would still buy it. The only thing I'm looking forward to the Note 5 would be hopefully a switch to USB 3.1 Type C.

There is only one phone that will potentially have removable batteries and Micro SD cards. So far LG screwed up the LG Flex 2. You're just making your choices very limited.
Consider those options dead until more than one manufacture brings them back in flagships.
